1 Claim.

This invention relates to new and useful improvements in sash retainers.

The principal object of the present invention is to provide a simple device which can be attached to the usual sash fastener so that the lower sash can be raised and held in raised position without likelihood that a burglar can reach under the lower sash and unfasten the window. Another important object of the invention is to provide a sash retainer of the character stated which will be more durable and satisfactory in use than conventional types of retainers now on the market.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawing:

Figure 1 represents a fragmentary vertical sectional view through a window construction showing the lower sash in elevated position.

Figure 2 represents an outside elevational view of the retainer plate.

Figure 3 is a longitudinal sectional view through the retainer plate.

Referring to the drawing wherein like numerals designate like parts, it can be seen in Figure 1 that numeral 5 generally refers to the usual window frame having the lower sash guideway 6 and the upper sash guideway I in which the lower sash 8 and upper sash 9, respectively, are

slidable.

In carrying out the present invention, the usual cam and keeper type of fastener for the sash is employed, the keeper being denoted by the numeral 9 and being of the hook type while the cam is denoted by reference character I0 and is swingably secured to the sash plate II by the pin or screw I2.

The present invention consists of the elongated plate I3 having the struck out area at its lower end portion bent outwardly and curved to define the tongue II for engaging the neck portion of the keeper 9 and the opening I5 through which the head portion of the keeper 9 extends. As a matter of fact, this opening l5 and tongue I I may be regarded as defining a yoke portion I 6 for engaging the hook-shaped keeper 9.

At vertically spaced intervals on the plate I3 5 are the slots generally referred to by numeral IT for receiving the cam I0. Each of these slots II consists of a pair of transversely spaced openings |8-I9 connected by a transversely extending slot in which the usual horizontal web p01'- 10 tion of the cam I0 is movable. The openings I8 are substantially smaller than the openings l9 so that the cam can pass through the larger opening I9 and its smaller end pass into the smaller opening I8 and thus camming action will be af- 15 forded against the lip 20. The lip 20 is pro vided so as to afford a sill for the cam I0, thus reinforcing the plate at the slot I1 and also reducing wear at these points.

While the foregoing specification sets forth the 20 invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter. 25

Having described the invention, what is claimed as new is:--

A window sash retainer for use in connection with sashes having a rotatable cam fastener and a keeper therefor; said retainer comprising an 30 elongated plate having an opening in one end portion thereof and a hook-shaped structure extending from the plate at the upper end of the opening and adapted to hook over the back portion of a window keeper while the forward por- 5 tion of the keeper projects through the said opening to hold the said plate in an upright position, the upper portion of the plate being stamped to form a transverse slot and an outstanding lip at the intermediate portion of the said slot, said 40 lip defining an aliner for the cam fastener with respect to the slot.
